For years it was assumed that Cheney masterminded the leak in an effort to discredit Plame's husband, former Ambassador Joseph C. Wilson IV, whose reports out of Niger threw doubt on White House claims that Iraq was importing ingredients to make weapons of mass destruction. Now, in just-released documents, the FBI concludes that Cheney told Libby and his press secretary, Cathie Martin, about Plame's ID about a month before the news hit the papers.

But the amazing thing about the FBI documents describing Cheney's 2004 interviews with investigators is how often he employs the "I don't recall" line.

Cheney told the FBI he did not recall discussing Plame with Libby prior to her name being published in a column by Robert Novak in July 2003, and said he had no knowledge of Libby's meeting with New York Times reporter Judith Miller before Plame was identified in that paper.

Oh, and the former vice president didn't recall about two dozen other events he was involved in.
